So after further testing,it's not the mercury switch. It's the wire inside the main cable from the box to the side of the engine. This isn't going to be fun assuming I redo the entire cable. I could always bypass the cable for that one connection. Or try to make a new one.
Hard to tell really. I'll have to check that out. They are the original so it's possible that they went bad.
Cleaning the grease off and the solder point looks great. No burning or anything. I tried to test continuity from the post to the solder point but didn't register. It's possible the...
We're on the same page. The first one should complete the ground to the starter. Just trying to figure out how to ground it. I assume I can bypass it by completing the circuit from the small post to the ground on the starter.
Which works like a charm. So it's the mercury switch and not the...
Throttle in slow, gear in neutral, mercury switches in the up position, nothing.
I assume that the one with the single wire is the one to ground? According to the schematic, the one with two has one that goes to the cutoff and another grounded to the frame of the engine.
Testing voltage from the battery grnd to the large battery terminal on the solenoid gives 13.5v .
Nothing on the first ignition wire until I turn the key. Then 12.9v on it, and on the second small terminal 12.5 v with the key on. No clicking.
Hmmm ok I'll try that. Have to find that switch. I have the PDF of the manual. So it shouldn't be that hard.
Edit:
Is it the cut out switch in the manual?
So I get voltage across the two ignition terminals when I turn the key but no voltage on the starter side large cable. 12.9 v on the terminals.
Continuity between the small terminals doesn't drop to zero like it should though.
